.Be'it known that I, C,oN JAMES VAsoREsN,

coir-Jams tasaammor MoGoLtoN, NEW C rormnna Application filed mmn "r1,.192a: Serial No. 623,456.

a citij'ei'iof the United States, and'a resident of liiogollon in thecounty ofCatron and .Sta t e.',of New Mexico, have invented'new and'iiseful Improvements in Clothes Poundervs,'. of .which the following isa full, clear, andexa'ct description.

The general object of this invention is the provision of ,a.,simple andefficient clothes 'pounder provided with means for forcing air and waterthrough the .articles to be washed to carry outthe cleansing operation.This object is accomplished by providing a casing, in the lower end ofwhich a cylininder a piston provided with an expansible piston ring, andproviding, in con unction with the piston, means for operating it.

I These and other objects of the invention .will be more clearlyunderstood from the following detailed description and accomline 11,Figure 2;

ings, the invention includes a casin panying drawings.

Figure 1 is a vertical section along the p Figure 2 is a transversesection along the line 22, Figure 1.

Referring to the abovementioned drawthe shape of a truncated cone. Formein the lower end of the casing is a cylinder 12 having a transverse wall24 constituting its head extending across its upper end. A plu rality oflateral openin s 11' are rovided in the upper portion of t e casing aove the wall 24. Slidably mounted in the cylinder 12 is a piston 13, inthe upper portion of which a circumferential groove 23 is formed. Formedintegral with the piston 13 is a hub having an internal thread. Avertical shaft 15, the lower end of which is threaded i at 26, isslidably mounted in the casing projecting through an opening 27in thetransverse wall or head 24, the threaded ortion' engaging the internalthread of the ub 25. Attached to the upper end of the vertical shaft 15is a handle 16 for operating it.

Mounted on the vertical shaft 15, the lower end resting on thetransverse Wall or head 24, is a spring 17. The 'upper end of thisspring engages a pin 18 projected through an opening in the shaft 15.Two washers 19 and 20 are mounted on the shaft and supported by the in18. These washers are made from rub er or some similar material so thatas the vertical shaft 15 is pro- 'jected upward they will receive a ndcushion the pin 18 and prevent noise. A- piston ring 21 having integraltherewith an inwardly extending annularflange .14 is mounted on thepiston 13, the annular flange 14 fitting in the circumferential groove23, and the diameter of this ring is suchthat it has a z loose slidingfit in thecylinder. The lower edge 22 of the piston ring 21 projectsbelow the piston 13. The piston ring is made from i amaterial'possessing a certain amount of elasticity so that on thedownward stroke of the piston the piston rin spreads outward, sweepinthe walls of t e cylinder 12. On the upwar stroke of the-piston thewalls of the piston ring 21 tend to collapse, al-

lowing air to pass down between the piston ring and the cylinder wall.

The operation of this device is as follows:

The clothes pounder is projected into the wash water, placing the mouthof the casing 10 over the articles to be washed. The vertical shaft 15is then forced downwardly operating the piston 13. As the piston 13moves downward, the lower portion of the piston ring spreads outward,sweeping the sides of the cylinder 12, and forcing air and water throughthe articles to be washed. This passage of air and water through thearticles to be washed carries on the washing process. Air flows into thecasing through the openings 11 and into the cylinder through theopenings 27. When the piston is drawn upward the piston ring 21 tends tocollapse and allows air to pass between it and the walls of thecylinder. The piston is given its upward movement by the spring 17 whichis compressed or ener ized on the .downward movement of the sha t 15.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the exact details herein illustrated since manifestlythe same can be considerably varied without de arting from the spirit ofthe invention as efined in the appended claims.

Claims:

1. A device of the character described, comprisin a casing the shape ofa truncated cone and aving lateral air inlet openings in its upperportion, a cylinder having a top wall rovided with a relatively largecentral opening therethrough, and located near the bottom of saidcasing, a piston having an expansible piston ring mounted thereon andloosely and slidably mounted in the cylinder,

and means for operating the piston.

2. A washing device of the character described, comprlsing'a truncatedcone-shaped casing. a cyhnder formed in the lower portion of saidcasing, a piston loosely slidably mounted in said cylinder, anexpansible piston ring mounted on the piston, a wall" formed integralwith the casing and ex tending transversely across the upper endati'vely -large central opening therethrough, a ver-' of the cylinder,said wall having a r tical shaft slidably mounted inthe casing and insaid wall and connected to said piston for operating it, and a springmounted on .said shaft within the casing' hearing at one end on saidtransverse wall and connected to the vertical shaft for giving thevertical shaft its upward movement.'

'3. A washing device oi the character de- '0 scribed comprisin'a-truncated cone-shaped casing having a ey inder'foi'med in its lower 4portion, thefcylinder head having a central opening therethrough, aiston loosely and,

slidably mounted in sai' eiylinder, an expansible iston rm mounte onsaid iston,

-a vertica shaft sli ably mounted in te casported by said pin, and acoil spring mounted on said washer within the casin and co-operatingwith the vertical shaft and the head of the aforesaid cylinder to give35 the shaft its upward movement.
